Ricardo Sueiras is a self-professed "IT professional and geek" (found that on his blog. His formal title is J2EE Systems Architect at PricewaterhouseCoopers LLP in Canterbury, United Kingdom.

The following is an interview with Dr. J Singh, and he shares his thoughts with us on software testing.

Dr. J Singh is a principal of Quantitecture and 20+ year veteran with extensive experience with system performance. Dr. Singh has served as a technology leader at several companies, including the Director of Software Development at Fidelity Investments. He is a wise, yet humble, man that prefers to be called J rather than Dr. Singh. Being a lifelong basketball fan, I would prefer to call him Dr. J. :)

This is the third installment of an email interview with James Christie, software testing professional from Scotland. In the first part, James talks about his views on usability testing. In the second part he discusses leaders in usability testing, KPIs, test automation tools, cloud computing, and testing blogs.

James mainly discusses load testing in this last post. It's my favorite segment. ;)

What would you say is the difference between load testing and performance testing?

I’d say performance testing is a general term that covers load testing too. Performance testing is a rather vague term covering response times and the application's ability to cope with heavy loads. Load testing is a more specific term. I think of it as a technique to allow you to carry out performance testing effectively. You either work your way up through a series of load levels establishing how the application performs, or hit it with the maximum loads it will have to cope with (plus a bit more to allow a margin for error).

I recently found and joined The Software Testing Club, an online community of software testers. The site has some very good video interviews of leaders in the industry.
